Power Supplies are Class I, Div. 2 Rated for use in Hazardous & Explosive Locations

Description

Lambda has introduced a series of Class I, Div. 2 rated DIN Rail-mount AC-DC power supplies available with a choice of output voltages from 5 to 48 volts. The low power DPP series is an economical solution and specifically designed for use in industrial applications including hazardous environments and explosive gas atmospheres such as those found in chemical and petrochemical plants as well as pumping and distribution stations.
Lambda's DPP series includes 6 models with Class I, Div. 2, Groups A, B, C and D ratings; enclosed in rugged insulated cases that are only 2.95” H x 1.77” W x 3.58” D.   These ANSI/ISA12.12 certified supplies include the following models (volts/amps): DPP25-5 (5V/5A), DPP30-12 (12V/2.5A), DPP50-15 (15V/3.4A), DPP30-24 (24V/1.3A), DPP50-24 (24V/2.1A) and DPP50-48 (48V/1.01A).  The addition of the “UL1604” suffix to these model numbers will insure the proper UL label will be provided (e.g., DPP50-48 UL1604).
Each model can operate worldwide with a broad range of AC inputs from 85 to 264 volts AC without the need for pre-selecting the AC input range.  In addition, these units will operate from a DC input ranging from 90 to 375 volts DC.
The supplies feature a low ripple and noise of 50 millivolts or less and are protected against over-current and over-voltage conditions.  In addition the supplies meet EN55022 Class B EMI standards (radiated and conducted), are certified to UL/EN60950-1 specifications, are listed to UL508 and CE Marked.
The units are convection cooled and can operate at full output power over a wide temperature range of from -10°C to +71°C, with derating above 60°C. Typical operating efficiencies reach up to 87%.  The units can be mounted on either a TS35/7.5 or TS35/15 standard DIN rail.
